Spike Chunsoft initially published the action game in Japan late last year, and plans to release an enhanced version subtitled Chain in the country this December.

Attack on Titan is a popular manga and anime series set in a world where gigantic humanoid creatures have driven humanity to near-extinction. The last vestiges of mankind are left to hide behind a series of walls while the armed forces search for a way to defeat the cryptic predators.
